I just filled my raised bed in with mulch. I added cheap potting soil with perlite to the hole. To me the perlite is easier because it is not as heavy as sand and the drainage is awesome. Also it is cheap. (Do not inhale the dust!!!)
The stuff we get here and the stuff you get there might be different depending on the distribution center and where it is manufactured. The Scotts top soil that comes in here is nasty. It has rocks and crazy mess in there. Bad reviews, but I see that people in other states love the stuff and brag about it.
